Shaxda tusmada
Nebi cad oo naadir ah, sida kan lagu sawiray suugaanta caadiga ah ee "Moby Dick", ayaa lagu arkay xeebta Jamaica. Badmareenadii la socday markabka shidaalka qaada ee Coral EnergICE ayaa arkay cetacean-ka rooxaanta ah 29-kii Noofambar, markii Captain Leo van Toly uu duubay muuqaal gaaban oo muujinaya muuqaal kooban oo uu ku eegayo nibiriga shahwada cad ee u dhow biyaha dushiisa. Waxa uu muuqaalka u diray rafiiqiisa badmaaxinta, Annemarie van den Berg, oo ah agaasimaha ururka samafalka SOS Dolfijn ee ilaalinta nibiriga Nederlaan. Ka dib markii ay xaqiijisay khubarada in nibirigu uu dhab ahaantii ahaa xawadii, SOS Dolfijn waxay la wadaagtay muuqaalka bogga Facebook ee ururka.
1>Buuga caanka ah ee Herman Melville, Moby Dick waa shahwo cad oo bahal ah oo uu ugaarsado Kabtankii Ahab ee aargoosiga ahaa, kaas oo lugtiisa ku waayay nibiriga ilka leh. Buuga waxa wariyey naakhuudihii Ismaaciil, oo ku caan baxay yidhi: “Waxay iga nixisay cadaankii nibiriga”, isaga oo ula jeeda midabkiisa. Inkastoo Moby Dick uu ahaa khayaali, nibiriyada shahwada cad waa dhab. Cadaanimadoodu waa natiijada albinism ama leucism; Labada xaaladoodba waxay saameeyaan awoodda nibiriga si ay u soo saaraan midabka melanin, kaas oo ka masuul ah midabkooda caadiga ah.

"Laakiin mar mar waa la arkaa."- Muqaal cajiib ah ayaa muujinaya kalgacal u dhexeeya lammaanaha iyo nibiriyada humpback Daawo muuqaalka cajiibka ah
Maadaama baddu aad u balaadhan tahay, saynisyahanadu ma hubaan inta ay le’eg yihiin nibiriyada shahwada cad ee jira, ayuu yidhi Gero. nibiriga shahwada ( Physeter macrocephalus ) ayaa sidoo kale ah kuwo aad loo fahmi karo oo ay adagtahay in wax la barto taas oo ay ugu wacan tahay awoodda ay u leeyihiin in ay si qoto dheer ugu quusaan badda muddo dheer. "Waa ay fududahay in nibiriga uu qariyo, xitaa mid ilaa baska dugsiga," Gero ayaa yidhi. "Sidaas darteed xitaa haddii ay jiraan tiro badan oo nibiriyada shahwada cad, ma aragno marar badan."
Aragti kale
Aragtidii ugu dambeysay ee la diiwaangeliyay ee nibiriga shahwada cad waxay dhacday 2015 jasiiradda Sardinia ee dalka Talyaaniga. Si kastaba ha ahaatee, waxaa sidoo kale jiray muuqaalo Dominica (Kariibiyaanka) iyo Azores (ee Atlantic) sanadihii ugu dambeeyay, ayuu yiri Gero. Waxaa laga yaabaa in kan Jamaica lagu arkay uu la mid yahay Dominica, laakiin taasi ma cadda, ayuu raaciyay.

(Sawirka: Gojiraiwa Whale WatchingKanko)Sidoo kale waxaa jira muuqaal marmar ah oo ah nibiriyada cad cad oo ka mid ah noocyada kale (marka lagu daro belugas, oo midabkiisa caadiga ah uu yahay caddaan). Whale albino humpback ah oo la yiraahdo Migaloo ayaa si joogta ah loogu arkay biyaha Australia tan iyo 1991, sida ay sheegtay Hay'adda Whale Pacific. Bishii Luulyo, ilaaliyaasha nibiriga ee Japan ayaa arkay labo ka mid ah nibiriyada dilaaga cad, kuwaas oo u badan tahay albinos, Live Science ayaa sheegay wakhtigaas.
White Whales
Whales White waxay leeyihiin albinism ama leucism. Albinism waa xaalad hidde-side ah oo xayawaanku aanu soo saari karin melanin, midabka midabka siiya maqaarka iyo timaha, taas oo keenta in guud ahaan midab la'aanta shakhsiga ay saameysay. Leucism waa la mid, laakiin waxay saamaysaa wax soo saarka melanin ee unugyada midabka shakhsi ahaaneed, taas oo keeni karta lumin buuxda ama qayb ahaan midabka. Sidaa darteed, nibiriyada leh leucism-ka waxaa laga yaabaa inay si buuxda u caddaan ama ay leeyihiin balastar cad. Cilmi-baarayaasha qaar ayaa aaminsan in midabka isha uu sidoo kale kala saari karo labada xaaladood, sababtoo ah inta badan nibiriyada albino waxay leeyihiin indho cas, laakiin taasi ma ahan dammaanad, ayuu yiri Gero. "Whale-ka Jamaica waa mid aad u cad, malahaygana waa albino - laakiin taasi waa uun mala-awaalkayga," ayuu yiri Gero.
Moby Dick
Go'aanka Melville ee ah inuu Moby Dick ka dhigo caddaan. Dadka qaar ayaa aaminsan inuu ahaaiyagoo dhaleeceynaya ganacsiga addoonta, halka qaar kalena ay sheeganayaan in loo sameeyay masraxa si gaar ah, sida uu sheegay The Guardian. Si kastaba ha ahaatee, Gero, muhiimada Moby Dick ma ahayn midabaynta nibiriga, laakiin sida buuggu u muujinayo xidhiidhka ka dhexeeya bini'aadamka iyo nibiriyada shahwada.

Wakhtigii buugga la qoray 1851-kii, nibiriyada shahwada ayaa adduunka oo dhan looga ugaarsanayay saliid aad qaali u ah oo ku jirta lubabka. Tani maaha oo kaliya in noocyada ay ku riixday inay qarka u saaran yihiin inay dabar go'aan, laakiin waxay sidoo kale ku riixday bini'aadamka inay horumariyaan ilo cusub oo tamar ah iyo tiknoolajiyada la xidhiidha iyaga. "Haddii aysan ahaan lahayn nibiriyada shahwada, da'deenna warshaduhu aad bay uga duwanaan lahayd," ayuu yidhi Gero. "Kahor shidaalka fosil, nibiriyadani waxay awoodeen dhaqaalaheena, waxay ku shaqeynayeen mashiinadayada waxayna iftiimiyeen habeenkeena."

Nibiriyada shahwada ayaa hadda lagu taxay inay yihiin kuwo u nugul dabar-goynta, laakiin tiradooda saxda ah iyo isbeddellada dadwaynaha adduunka ayaa si liidata loo fahmay xog la'aan awgeed, sida ay sheegtay Ururka Caalamiga ah ee Ilaalinta Dabeecadda (IUCN)
